The identification card provided by this embodiment has higher material hardness and structural strength, and is not easy to deform due to the adoption of ceramic substrate.
The marking part 22 may be a functional module for user identification, such as a chip, a magnetic stripe, a signature strip, a bank logo or an anti-counterfeit label, and the bearing layer 21 may be made of one of or the combination of PVC (Polyvinyl chloride), PET (Polyethylene terephthalate), ABS (Styrene resin), or other resin materials. The bearing layer 21 has a sheet structure for bearing the marking part 22, and the bearing layer 21 and the marking part 22 can be formed into an integrated structure by stamping or other processes. Specifically, at first, a plurality of marking parts 22 are uniformly arranged on a large bearing layer 21, and then an integrated structure including the large bearing layer 21 and a plurality of marking parts 22 is formed by stamping or other processes, and at last an integrated structure including only one marking part 22 is formed by stamping, cutting or other processes to improve production efficiency. After that, the formed integrated structure is connected with the accommodating part by gluing.
Referring to FIG. 2 , in some optional embodiments, the ceramic substrate 1 includes a first ceramic substrate 11 and a second ceramic substrate 12 that are connected with each other, and the accommodating part is arranged on at least one of the first ceramic substrate 11 and the second ceramic substrate 12.
It can be understood that the first ceramic substrate 11 and the second ceramic substrate 12 are attached to each other to form the ceramic substrate 1, and the accommodating part is located on the surface opposite to the other of the first ceramic substrate 11 or the second ceramic substrate 12, i.e., the accommodating part may be a closed space, and the marking joint part 2 can be fixed between the first ceramic substrate 11 and the second ceramic substrate 12, or a through hole can be perforated on the first ceramic substrate 11 or the second ceramic substrate 12 to expose the marking part 22 of the marking joint part 2 to the outside to facilitate identifying.
In addition to the above-mentioned split structure in which the ceramic substrate 1 includes the first ceramic substrate 11 and the second ceramic substrate 12, the ceramic substrate 1 may also adopt an integrated structure as shown in FIG. 1 , i.e., the ceramic substrate 1 has an integral sheet-like structure, herein an accommodating part is directly arranged on the outer surface of the ceramic substrate 1, and the marking joint part 2 is connected with the ceramic substrate 1 by gluing or other processes.

Optionally, an adhesive layer or a 3D printing layer can be arranged between the marking part 22 and the inner wall of the through hole for fixing and connecting, so as to prevent the marking part 22 from moving during use.
In order to further improve the connection stability between various parts of the identification card, in some optional embodiments, adhesive layers are provided between the accommodating part and the marking part 22, and between the first ceramic substrate 11 and the second ceramic substrate 12.
Specifically, the shape and size of the adhesive layer are matched with the shape and sizes of the accommodating part, the first ceramic substrate 11 or the second ceramic substrate 12, so as to ensure an enough contact area between the adhesive layer and each component, thus improving the bonding effect.
Optionally, a stereoscopic printing layer is provided at the joint between the first ceramic substrate 11 and the second ceramic substrate 12, and the stereoscopic printing layer is a film formed by a 3D printing process, and can effectively connect the first ceramic substrate 11 and the second ceramic substrate 12 to avoid separation of the first ceramic substrate 11 from the second ceramic substrate 12.
